Overview

Standard Ignition S2620 is a tail light wiring harness for the right side of select GMC trucks. It uses a rectangular single-connector layout with four blade terminals and 20-gauge wire for a direct electrical connection at the lamp assembly.

Key Features

  • Tail light wiring harness with a 76-inch harness length for routing to the rear lamp area.
  • Rectangular connector design with one connector and four blade terminals.
  • 20-gauge, four-wire construction for the tail light circuit.
  • Male connector and female terminal configuration for secure mating.
  • Fits 2014-2015 GMC Sierra 1500, right; 2015 GMC Sierra 2500 HD, right; 2015 GMC Sierra 3500 HD, right.

Detailed Description

Standard Ignition S2620 is built for right-side tail light service on compatible GMC Sierra applications. The harness length, connector shape, and terminal layout are specified to match the electrical connection point at the lamp, helping restore a clean signal path when the original harness is damaged, corroded, or no longer making reliable contact. This part cross-references Monroe Shocks & Struts (e.g., LS2520, PT2606) for the same application. Standard Ignition S2620 is a practical replacement for technicians working on 2014-2015 GMC Sierra 1500 and 2015 GMC Sierra 2500 HD or Sierra 3500 HD rear lighting repairs.

Common Uses

  • Broken or cracked tail light wiring at the lamp connection.
  • Intermittent rear lighting caused by worn terminals.
  • Corrosion at the connector or terminal interface.
  • Electrical repair after harness damage from heat, moisture, or abrasion.

Installation Notes

Verify connector shape, terminal count, and wire routing before installation. Match the right-side application and confirm the harness reaches the original lamp connection without strain. Inspect the mating connector and surrounding wiring for corrosion or damage before final assembly.

Quality Assurance

Standard Ignition supplies electrical replacement parts for service applications, and S2620 is built to match the specified connector and terminal configuration for the listed fitments.
